IBLEACHING-KEIR.

SPECIFICATION forming part of Letters Patent No. 302,138, dated July 15,1884.

Application filed January 28, 1884. (No model.) Patented in England June14, 1883, No. 2,958; in France December 13, 1883,

No. 159,160; in Belgium December 18, 1883, No. 63,580, andin ItalyJanuary 19, 1884, No. 16,342.

To all whom, it may concern:

Be it known that we, CHARLES LoXToN JAoKsoN and JAMES WESTLEY, subjectsof the Queen of Great Britain and Ireland, and residing at Bolton, inthe county of Lancaster, England, have invented Improvements in theConstruction of Bleaching-Keirs, (for which we obtained a patent inGreat Britain, No. 2,958, dated June 14, 1883,) of which the followingis a specification.

Our invention relates to the construction of keirs employed forbleaching; and it consists, principally, of improvements to be appliedto that part of the keir known as the pufferpipe, the object of the saidinvention being to prevent theboilingup of the liquor through the clothor other material under operation, and to cause the said liquor to bedelivered in a continuous stream upon the top of the cloth or othermaterial, and be drawn downward through the same.

The invention is applicable'both to heirs wherein the puffer'pipe isplaced inside the keir, and also to those wherein the puffer-pipe isoutside the same. I

In the annexed drawings the invention is shown,for the sake ofillustration, as it would be when applied to the inside of a keir.

- Figure 1 is a vertical section of. the form of the improved apparatuswhich we find most convenient for general purposes. bottom end of thepuffer-pipe a a is reduced in diameter, so as to form a kind of throat;or, as shown at Fig. 1, it is fitted onto athroatpiece, I) b, bolted tothe upper flange of the casting c c, and the lower edge of the same isbeveled off in the interior, as at d d. The upper end of the steam-pipee e in the liquorwell is provided with a hollow nozzle, f f, madeconical on the outside, and projecting slightly into the beveled mouthdd of the puffer-pipe, leaving a conical'annular space, 9 9, between thetwo, through which the liquor entering the casting c c by the openings hh is forced (by the suction or vacuum formed by the rush of the steamthrough the nozzle f f) up the puffer-pipe a a. There is also a The'cross pipe or passage, 1' z', or there may be ous stream, and the vacuumcaused therebyin the liquor-well will draw the hot liquor back againthrough the cloth or other material under operation. We provide thepufferpipe'at the top (by preference) with a bonnet in the form of aninverted dish, inside which we fit a perforated plate suspended by'studs,which assists greatly in the even distribution of the liquor overthe cloth or other material under operation; but to this bonnet we makeno claim as our invention. The course of the liquor is shown by theplain arrows, and that of the steam by the dotted arrows.

Fig. 2 shows a modification of the above, wherein an additionalsteam-pipe, N, is placed inside the vertical liquor-pipe k k.

Fig. 3 is a vertical section, and Fig. 4 a horizontal section, of amodification wherein the erosslpipe or passage M is dispensed with,andthe lower end of the y'erticalpipek 7c is carried through the. bottomof the steampipe 6 e, and is provided with a baffleplate, m m, whichprevents the return of the column of liquor.

' Figs.@5 and 6 show in the vertical and horizontal section a furthermodification, wherein the cross pipe or passage z t is made in an elbowform, instead of running straight across the steam-pipe.

Other modifications might. be made, to operate in substantially the samemanner, without departing from the distinctive features of ourinvention. r
